Military Fast Combat Army Safety Defense Tactical Helmet

A: Environment: Store in a cool, dry, and well-ventilated place, avoiding direct sunlight, heat sources (such as heaters), and strong acid or alkaline environments.
Placement: Do not hang it, as this can cause deformation of the suspension system due to prolonged stress. Lay it flat or use a dedicated stand.
Condition: All components (such as the face shield) should be in a relaxed, unstressed state. The inner liner is best removed and stored separately.
Regular Inspection: Even when not in use, inspect for signs of aging every quarter.

A: This is a critical compatibility issue.
Space compatibility: The helmet's chinliner must have sufficient space to accommodate the gas mask's sealing edge. Some helmets are designed with removable or ultra-thin liners to provide this space.
Vane compatibility: The fixed visor of the helmet usually needs to be removed or flipped up because the gas mask itself has an eyepiece. During testing, it must be ensured that the helmet does not compress the visor, causing air leakage.
